It's been a bit but last I was there the h st curb parking lane was barricaded off and had been for some time, so naturally the middle westbound travel lane was full of parked / loading vehicles leaving only one usable lane to drive on. Just a couple of years ago the entirety of H st was a rush hour no parking zone. It seems unlikely that particular Wal mart will get better over time. When they first opened everything was top notch there. Coming into the garage via 1st from K Street instead of H seems to be good to get around the standing vehicles blocking the garage.
